During tea season, Drunken Petals has been hosting tea-tasting banquets for consecutive days. Throughout the event, Revelry Hall randomly serves Huajian Ke one of three teas daily - Jingshan Tea, Qujiang Thin Slice, or Xianya Stone Blossom.
Each day carries 60% chance for Jingshan Tea, 20% for Qujiang Thin Slice, and 20% for Xianya Stone Blossom. Huajian Ke poses this challenge: On average, how many days are required to sample all three teas?
